The count of the 103-keV \(\gamma \)  peak was analyzed using Radware package [1]} and corrected with the dead time of DAQ.
Decay parameters of Ho isotopes, the decay constant (\(\lambda \) ) and the relative intensity (\(\eta _\gamma \) ) of the characteristic \(\gamma \)  ray, are from the Nuclear Data Sheets (NDS) [2]}.
By decoupling the total counts of characteristic \(\gamma \)  rays measured in both types of targets at the same proton energies, we can deduce the cross sections for \(^{160}\) Dy(\(p,\gamma \) )\(^{161}\) Ho and \(^{161}\) Dy(\(p,n\) )\(^{161}\) Ho. The derivation of cross section from the activation \(\gamma \)  rays is described in detail in Appendix A.
